The parents of murdered British teacher Lindsay Ann Hawker have made an emotional television appeal for help in finding her killer. The 22-year-old was found buried in a sand-filled bathtub in a Tokyo apartment in March. Speaking to the BBC, her parents, Bill and Julia, from Brandon, Warwickshire, said they had decided to speak to the media to bring their daughter's murder back into the public eye. Earlier this month, police released CCTV footage of suspect Tatsuya Ichihashi, 28. He fled from officers when they called on him at his apartment on March 26. The police have not been able to trace him. Press Association
